. SPECIFICATION forming part of Letters Patent No. 657,550, dated September 11, 1900.

Application filed October 8, 1898.

. To all whom it may concern.-

Be it known that I, CHESTERAL THAM, a citizen of the United States of America, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Bearings, of which the following is a specification, reference being bad therein to the accompanying drawing, and the figures of reference thereon, forming a part of this specification, in which the figure is a sectional View of a box with rollerswith ridges surrounding them in two directions and a shaft.

This invention relates to certain improvements in bearings; audit consists of rollers placed between the boxing and journal, said rollers having ridges surrounding them in both directions and the boxing with outlets in the under side; and the object of my invention is to produce a bearing that will run with the leastpossible friction.

Referring to the drawing, 1 represents a boxing. V

' 2 represents a shaft.

3 represents rollers having ridges 4 and 5 running around said rollers in opposite direct-ions from the ends toward the center. Said ridges may have a flat bearing-surface or they may have a round or oval bearing-surface. 6 represents a small space between said ridges 4and 5. 7 represents the ends'of said rollers, made either rounding or conical. 8 represents small openings in the under side of the boxing 1. 9 represents a collar, which may be made in any suitable shape or form.

Seria1No.693,018. (No model.)

Said ridges surround said rollers in opposite directions for the purpose of preventing the tendency of an end thrust. Said openings 8 are to allow auy'foreign substance dropping out which would be worked to the center or to either end by the ridges at and 5.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is as follows:

1. In combination with a journal with acontinuous smooth surface and a boxing with a continuous smooth surface, solid rollers having the rounded ends,a series of uniform spiral ridges surrounding said rollers from one end to a point near the center in one direction, a

like series of spiral ridges surrounding said rollers in the opposite direction from the opface, and small openings in the under side E. E. ENooH, A. A. GLENN.
